I feel iffy about the example ship section, especially since the examples are from only one fandom. Perhaps the list should mention fandoms where there's a lot of antishipper activity.
Another thought: This isn't the same phenomenon exactly (or is it??), but seems related to some of the TJLC wank and Sherlock 221b con wank in 2015, where fans were accusing other fans of p~dophilia. I also found an August 2015 example of fans creating a new ship_manifesto on tumblr, but disallowing "Abusive Ships" and "large age differences" About Us, Archived version LJ fans were taken aback.--aethel (talk) 03:38, 6 July 2017 (UTC)
